good point....i was just wondering if its worth it. i mean the bottle wont go empty after 10 runs or so right? on average im saying

 

Here's a comparison:
Running a 75 Shot
Using it From FIRST to Fourth in the quarter
I get like around 13-15 full passes with it

 

damn it seems to last a long time.......i mean for $35

 

obsolete, im assuming with your new block you'll probably decide to push a bigger shot, which is a great idea, just watch your valve overlap so your not losing any of your gas, and yeah, 50 shots are pretty safe, i would even say a 75 won't hurt a bit, just make sure you add more fuel
