[AMPS] pi vs. t tuned input

[Scott Townley]

About tuned input sections for amplifiers:
Everybody and their dog seems to have an affinity for the pi-net type of
tuned input.
Is there some practical reason not to use a T-net?
I was thinking of using molded chokes that are easily found from Digikey,
Mouser, etc., for the inductors...typical values in the 1.0-7.5uH range are
cheap, are rated for 500-600mAdc, and have RF-tested Q's of 35-40.  Which
isn't much, but is more than sufficient for a network with a loaded Q of
between 2 and 5.  
Or are these molded chokes weak in some aspect?  Should I "roll my own" on
powdered iron toroids?
Looking forward to any comments/observations.  
Thanks!
