The Cricket is more pinpoint than a Minor, the mini cc even bushier.
What is your oxy source going to be?
A Minor will work on one 5 lpm but rocks with 2 and even better with a 10lpm. The newer torches don't really lose much in value, so it's not like you are stuck with it if you want to sell it.
If you really want to do Boro I'd go with at least a small 4 stud torch, Hellcat, Scorpion, Bravo, of course it's going to cost you 310% more, but you won't be wanting to upgrade right away
(YEAH that's BS kinda like threefootitis in boats!)
