PD Jammers vs. PD T2 Clip-ons

I have been running a set of PD Jammers on my roadie getting ready for IMWI.  I had a good fit done and have started spending more time in the Jammers the last several weeks.  My experience thus far is that after a few minutes in the aero position my forearms get sore and I feel like my hands/wrists are "jammed" up possibly due to the steep upward angle on the Jammers. (Maybe thats why they call them Jammers).  I talked to my fitter and he said that I can certainly come back and he will work with me, but I don't want to start tweaking my fit until I get more miles in.  Some of it is getting my upper body used to having more weight on it vs. my former classic road position.

So my question to all of you out there is: Have you had similar experiences and if so what did you do?  If you switched to the T2's did it correct the problem?

My fitter did say that the T2's have a lot of adjustability and those are what he recommends if the Jammers won't work for me.

Thanks for the input!
