Which RF amps do you have? Which PG amps were you thinking of upgrading to? I think that may affect everyone's opinion on which one you should go with. I would hate to suggest getting rid of a bd1500 to get a lower watt PG. IMHO, PGs newer amps look really nice. I hate that RF just changes the look of the heatsink/housing and says it's brand new. I have a pair of 120@2s(the black and silver triangular style ones) and when they came out with the rounded ones a RF dealer tried to convince me the "new" 120.2s are more powerful than mine. What a dumb@$$.
