Similar Geometries, Different Components

So, I've been to 4 Local bike shops in the last couple days and have test-ridden around 6 HT XC bikes in the ~$800 range. The bike I liked best was the 05 Gaint Rainier. It's light, has decent components and just feels fun. In particular I like the frame geometry (XTC) better than any of the other bikes I test rode.

Now here's the issue: yesterday evening I take a look at the IBEX website and find that the Trophy-series frame geometry seems very close to the Rainier geometry.

Rainier- Trophy
Size: 19" - 20"
Head Angle: 71- 70
Seat Angle: 72- 73
Top Tube: 23.2"- 22"
Chainstay: 16.7"- 16.75"
WheelBase: 41.7"- 42"
Standover: 31.7"- 31"

The specs of each bike are:

_ 05 Giant Rainier_

Seat Post:

-------------------------------------------------

The Trophy works out to be about $100 less (shipping vs LBS tax considered). Of course I won't be able to test it until it arrives at my doorstep. It doesn't have the Hayes disc brake, but it does have what looks to be a better fork. I have no problem servicing my own bike as I am technically inclined. The LBS would provide "minor" adjustments for life on the Giant.

Based on the specs and the close geometry, what would you guys go with?

Thanks.. (Excuse the huge post)

Those specs aren't as "close" as you think The seat angle. head angle and the shorter top tube will feel a lot different than the Raineir that you seemed to like so much. Components are swappable, frame geometry is a PITA th get around. Bottom line get the Giant as you know you like it.

Thanks for the response, you're right- saving $100 dollars isn't worth the risk of an incompatible frame. If I ended up not liking the IBEX I'd be out ~$60-80 on shipping both ways too.

On another note, does anyone know if the Rainier frame is just a repainted copy of the entry level XTC frame? The geometries match 1 to 1, they're both made of ALUXX butted aluminum, is there a difference here?
