I should add, I have an AEE dipole in the nose about 8 inches from my feet, but despite 200 watts tested radiated power from the Trig 21, it does not keep my feet warm...

Ive noticed a marked change in my sex drive with anything past 200 watts..
Seriously, to get back to the OP, I was thinking of a Trig for the ADS-b out capabilities and the PF for the ADS-B in. This way my set up will not become obsolete in a few years. Am I correct on this assumption?
