advice for free flying

[tred 0]

so it seems most recommend the tunnel for learning backflying/sitflying, I am pretty close to ifly Orlando so I can go there. I have ten minutes in the tunnel (all on belly), 69 jumps mostly belly w/ 5 jumps backflying on my own and 3 attempting to sit (1 with a coach).

My question is, does anyone having any recommendations for good tunnel coaches to get the most for my money. PM if preferred.

Thanks for the help and any other advice is welcome
