On the question of open heart surgery recovery, it can vary from person to person, but of the two people I know who went through it (my Uncle for a valve replacement, and a very good friend for a triple-bypass), it's no easy matter. The very positive thing about it is, they have so much experience doing these things now, the risks are largely removed, and most people have a very positive prognosis long-term. Here's to a speedy recovery, in any case.
I ordered a bunch of V4L cartos, and didn't care for them. That's just my opinion, though, and I received a very kind offer from a regular here to purchase them from me, since I wouldn't be using them. There are people who like Coke (yuck) and people who like Pepsi. I happen to like Diet Pepsi.

That doesn't mean I begrudge anyone their choices.
And I think any rivalry, or '...... match', is largely overblown. Morandir can tell you he has been very well-accepted in this sub-forum, along with keelala (sp) girl.
We all choose KR808D PVs, and most of us used them to successfully quit smoking. That alone should bind us, not tear us apart due to whose product we choose to purchase.
