Sorry about that, I got you mixed up with someone else.
The Samsung 20S hits noticeably harder than even the Sony VTC5A, which used to be king of the hill in this regard as far as 18650 batteries are concerned. That is, until the Vapcell black 38A 2000mAh 18650 (which is a true 30A battery) came out:
Bench Test Results: Vapcell Black 38A 2000mAh 18650...bit overrated but incredible performer
But that one is superseded by the Samsung 20S. I own eighteen Sony VTC5A batteries, four Vapcell black 38A 2000mAh 18650 batteries, eight Vapcell black 25A 2800mAh 18650 batteries (which are rewraps of the Sony VTC5D), and twelve Samsung 20S batteries. And a whole bunch of bigger size batteries (20700, 21700, and 26650 batteries).
Only 260 watts is called plofessional?
I own two Wismec Reuleaux RX300 mods each one of which is capable of 400 watts. 
I just want to know what to expect. If Ill feel more power or not. If it hits faster on contact.
With your mod not being a full on mech/unregulated,if you do see a difference it will likely be slight.
I figured Id see a slight difference. Will the battery last less longer?
Without really knowing what mah your old batteries truely are, that is hard to say. Maybe, but since you are not maxing out the amps, they may run about the same. One way or the other, the new batteries will be safer since you will know what they are.
Compared to a pair of Sony VTC4 batteries, a pair of Samsung 20S batteries is going to give you a tad longer vaping time.
I have a good battery charger. Will it charge a 30 amp battery?
So I can actually build a build that will max the hex ohm out with its 30 amp batteries?
Yes, it will, as the CDR of a battery is associated with discharging the battery, not with charging it.
Here you can see that the Samsung 20S runs at a much higher voltage througout the entire discharge cycle when compared to the Sony VTC4.
If a battery runs at a higher voltage significantly for most of its discharge cycle, like these two charts are showing the Samsung 20S really does, you can expect the run time to be longer than what the mAh rating would have you believe. mAh = capacity, whereas Wh = energy. Wh, or watt-hours, equals mAh multiplied by 1000 multiplied by volts. (1000mAh = 1Ah.) For reasons that are obvious, having a higher capacity (mAh) gives a longer period of time before the energy runs out. But running at an overall higher voltage (i.e., being harder-hitting) gives more energy too, so basically that's how.
Please also note that when we vape at fairly high current levels, to prevent faster aging of the battery we don't vape the battery all the way down to 2.8V so to get an idea of the real-world vaping time you also have to take into account the voltage cut-off, which will be closer to 3.2V instead of 2.8V in this particular instance. It means you have to draw a horizontal line at 3.2V in these charts and remove the parts of the discharge curves below it. Next, compare the Sony VTC4 discharged at 20A continuously (blue line in the first chart) to the Samsung 20S discharged also at 20A continuously (green line in the second chart). As you can see, if discharged at 20A continuously, the Samsung 20S is just all the way above the Sony VTC4. To be able to do a similar comparison at 15A continuously, in the second chart you'd have to try to imagine a curve in between the red and green one because Mooch didn't test the Samsung 20S at 15A continuously, but despite he didn't test you can still clearly envision which battery is the winner. The Sony VTC4 is just an older battery that cannot hold its candle against the much newer Samsung 20S.
As of now 8 wraps heat up perfect. 9 wraps is a little slow. Will the 30 amp batteries heat up 9 wraps quicker?Yes, it will, as the CDR of a battery is associated with discharging the battery, not with charging it.

Not really. This is more a limitation of the mod you're using, as it still is limited by the fact it has a maximum output voltage of just 6V, but aside from getting an improved run-time, the key benefit of using the Samsung 20S is you'll be able to build your coil builds to less ohms (to get a higher maximum power output as a result from that) without going over the recommended safety limit of your batteries.

Want 9 waraps but Im wondering if tbe 30 amp batteries will fire them quicker. My buddy uses 9 wrap.
