Road Bike/Frame for 6'5" guy

After 5 years of riding Giant OCR's (currently an 06 OCR Composite XL frame), i'm thinking of trying something with more aggressive geometry. Mostly fitness cycling to date with solo and group rides, but seriously looking at joining a club and getting into some racing this summer.

Basically i'm looking to get some recommendations from similarly sized lads about what's been comfortable for them. Looking at carbon frame, Ultegra or DuraAce group. I'd have AU$4-5k all up to spend, but the closer to the $4k end the better!

Have taken a TCR and a Roubaix for a spin, but would be very open to "riding outside the box" with a lesser known sticker on the frame

I'm 6"2' and ride a Scott Speedster (Aluminium frame) and I love it. If you're looking for something more aggressive, go for Scott CR1 Plasma or a Cervelo P3 Carbon. Although, these are a bit pricey... You could try second hand, check out http://search.ebay.com.au/search/sea...ge=search&fgtp= or do a manual search via Ebay .com/.co.uk etc. Good luck
