multiple questions ~~

1. hmm i am on a site where you can watch your daily rake stats, so i dont know how other sites/meat deals with this, so i cant help sorry.

2. no idea, would be interested too though =)

5. i think mech is countered best by going mutas, terran is usually very unflexible if he goes mech so you can just outpower/outexpand him and go mass muta/hyd w upgr. , since he wont be able to harrass you a lot. depends on the map a lot ofc as well

1. and easy way (besides just using PT/HEM and converting) is looking at your FTPs. 7 points = 1$ of paid rake. So if your conversion (of the bonus) is x percent, just figure out how much rake in FTPs the site has charged you, and maybe compare that to your hem numbers before figuring your rb.

2.I go on the vent sometimes when I have long session days. sometimes I forget. msg me on skype.

3. I play was playing 1/2 for a bit but downswong this month. Overrolled so it's cool but rebuilding confidence at 100nl for the next week or 2. PM'd you if you'd still like to talk hands tho.

4. just buy it, you play 1/2. Say it takes you 1 hr of effort to search for that deal. You could have been grinding. =s

5. (horrible player now but used to be C+ way back on PGT. always an avid theorycrafter.)
afaik, main advantages of mech are in the versatility of the terran ball in rolling Z (and P's) ass over. so your game plan has to be to pick your battles well since mech's high dps in any mu means whole armies melt quickly, which is doable since you're more mobile. you know pretty much all this tho.
If I had to add anything, I'd highlight the fact that tank build time is a huge weakness. If you can pick off stray tanks, esp early, you'll have a much easier time delaying critical terran ball mass before you can tech to defilers + lategame army. (so go into the game with a plan of "power mutas -> win". he'll eventually outlast you)
