I'm getting two rba's, I've settled on the Trident for one, I'm also looking for a bottom feeder. I want something that is easy to work with, fairly inexpensive and has HUGE airflow, something to make clouds with, suggestions?
getting a couple rba's, help please

In all honesty, there aren't that many cheap rebuildables made for bottom feeding. You'll want something with side airflow, so you can at least drill it out. Your best option might just be a Reomizer, from Reos Mods. It's not stainless steel, which is what I usually prefer, but for a bit less than 50 bucks, you can't go wrong. I believe Rob (the owner of Reos Mods) can even drill out the air hole for you before he ships it.
I'm use a Trident clone and it's a great cloud machine if you set it up that way. You may want to drill out the 1.8 mm air holes a bit if you go real low in ohms.
For bottom feeding I agree with Richard. The RM2 is a great device and the Reo is a very good platform too.
Here's 3 bottom fed RBA's with screw on caps and are all excellent vapes:
On left is the Aero BF (dragonfly ecigs $94 shipped). It's SS and needs to be drilled for side air.
In center is a mark bugs chalice. SS & Ti. (Classifieds is the only place to find one if your stars are aligned). Comes with side hole.
On right is the REO RBA 2.0 / RM2 / REOmizer 2.0. (REOsmods.com $43 plus shipping). It's plated brass. Comes with a side air hole that's easy to enlarge.

I tried Ribbon and gave it away. I'd suggest 28 and 30 ga Kanthal A1 along with the ribbon. I've never used silica so I can't help with that
Sorry, I can't help with dual coils. I've never felt the need to try them. I also never used any thinner than 30 gauge.
Yep. 30 ga works fine. I prefer 28 ga cause I get more wraps. More wraps = more surface area = better VTF.
I only wrap micro coils with a inside diameter within the range on the chart below and tight / touching wraps, so using a .055" (roughly 1.4mm) jig it's right around 10 or 11 wraps.
I shoot to get about 10-13 wraps and use the gauge of wire that puts me in the resistance I want.
That means 28 ga for about 1.5 ohms and 30 ga for about 2 ohms.
I say "about" cause I stopped metering and it's hard to count these little wraps

For 1.5 ohm coils and over id recommend 30g kanthal.
Kanthal Wire 30 Gauge RW0107 - 100 FT 0.39oz Series A-1 Resistance AWG
I find when using 28g kanthal for coils over 1 ohm just takes too long to heat up, and I cant get the vape/clouds im looking for. I like 30g kanthal for coils over 1 ohm, and 28g kanthal for sub-ohm coils under 1 ohm...
