Transcend 143 vs Marek 146

I need some help guys. These are the two that I am debating. I know a lot of folks on here rave about the Transcend but the 146 Marek has me very interested. I'm 6'7 250 so the extra size sure wouldn't hurt. I have a chance to demo a 141 Marek in town but not a 146 and I'm not able to demo the Transcend either. Who out there has ridden both and can comment on the differences? FYI, I'm coming from an old Parks board that is just too inconsistant. I love the kick but progressing on that board has been a pain. Looking for something with a lot of pop but controlled and more consistant. Thanks!!!
