whats your thoughts on street stall speeds 727 info inside

ive called all the companies listed below
most of them all come in at 2500 after giving them the specs only one whos higher is ptc they say 2600 2800


hughes >>2500
ptc>>2600-2800
tci>>2200-2400
mancini they say use a tci 2400 to 2600 breakaway when i talked to tci they said its only comes in 2200 to 2400

tuff call when 4 out of 5 say 2500 i guess it would cause some one to lean that way
im really thinking of hughes or tci or maybe pct

any input from you guys as of the failures or problems with these 3??
ive ran the big dollar stuff from hughes in my power glide no issues but were far from a 2000$ converter
