Shank,
Not sure about temperatures, weather etc where you are at but if you can get out on course, what happens there is what really matters. LM numbers are but that, numbers. Of course, if you're still snowed out and suffering from cabin fever, I can see how this provides relief :-)
I put a Messenger in my Crazy 435. Don't know what the launch angle, spin and all those numbers are… Via my highly scientific and high tech 200 degree prescription glasses, I can tell you it flies lower than with the TJ46 though.. Seems to carry less and rolls more and overall consistent distance seems at least as good and probably slightly better. That's all that matters for ME. Was I launching and spinning too high with the TJ46 or am I launching too low and can have better carry with the Messenger? Maybe, maybe not… whichever gives me better overall consistent distance on course is what matters.
Just my 1 cent VAT included and of course, to each his own.
