Thanks Heather and Shawnette. I appreciate both of your feedback between the two torches.
I still don't know which one I will end up getting. The Scorpion was initially my bet (until the Sidewinder was introduced). The Sidewinder seems to be just a tad stronger and a little more than you "think" you need is never a bad thing right?
As well as already owning the Bob and being used to it's flame.
My plan is to run the centerfire off of a Regalia (my M-20 will stay with my current Bob for my daughter to use) and run the outerfire of off tank with a foot pedal.
Now I just need to build my studio at home and work on all the upgrades. Gotta win the lottery first (just a small one -- I'm not greedy).
