Shift Kits

i have my car at the tranny shop and i forgot to tell them i need a shift kit, so monday i will let them kno. whats the best out there? what about the Transgo Performance shift kit?
also the guy at the shop said that the fin type b&m tranny cooler has more flow restriction vs. the tube type, how much truth is there to that? mine tranny cooler is a 14,400btu, kinda small i would think, its got a low pressure bypass. i might just use it for an oil cooler.

i guess, i didnt kno if it was or not, i knew shift points and you can get rid of the timing retard, but it seemed like the tranny would take too much beating.
it will take me a while to get use to the tweecer so i kinda need a solution now.

they seemed very biast about what stuff they used. (they have a 4000hp car that runs 4sec in the 1/4 and nonight at No Problem raceway they said they might run 3's!!!!!!)
i was told they did very good work, so im not worried there. the first time i talked to them, he said c4 all the way, aode will not hold up. i need my overdrive so its not an option. when i brought the car the other morning, it idles real low at like 750rpms, b/c i got the TB set like that, it sounds cool lol i have had like 3 people say it was missing, then i rev it and they are like o its a cam LOL
so the tranny guy says its either running bad or you have too big of a cam. im like thats just the cam, its idles low. he looked at the cam specs and said my cam was too big, i kept my mouth closed. XE270HR-14, doubt it! lol
and my tranny cooler http://store.summitracing.com/partdetail.asp?autofilter=1&part=BMM-70264&N=700+115&autoview=sku
he said the fin type has more flow restriction than the tube type, he said go buy a tube type.
i got a remote tranny filter, he said the same thing about that and that its just another thing to clog up and cause problems. i kno they have done this and that and kno what works but **** mechanics that think they kno everything are *******s!
anyways whats your thoughts on the cooler suggestion?

mines 14,400btu's
yea i want all the performance from the trans as i can. idk about it spinning, i got dr's (which aint the best in wet conditions, tested it the other night, will spin if i gas it, but breaking is pretty good with them)
i can take it very easy but when i need those ass kicking shifts, i want it.
