Freestyle 148 or 155 Pump best for XFS/XS1000/PFP/Full Spes/MSD TL?

I'm at a cross roads right now, I've sold my Skat 144 pump and can go 148 or 155 in the below setup, which would you choose and why?

Glass 2012 XFS
XS1000 10mm
Power Factor Pipe
Full Spec 49 AVLR
MSD Total Loss

Believe there may be some 'shaving' of the pump tunnel required for the 155?

What else should I be considering?

Use 155mm pump better and use 8/16 or 9/17 pitch. 148mm pump is for 800cc-900cc. I sell 148mm pump just $1400 and 155mm pump is $1600. These are make from stainless steel in one piece. Contact me If you interesting. max_worachat@hotmail.com

Are external dims of 155 and 148 same as Skat or smaller?

Are they much heavier being Steel than Skat being Ali?

How much is shipping to UK?
 
I am running the same setup you are (only I have a DASA 10mm 1100) and I had the same question when I built my XFS ( just finished today). I called Thrust and they said that there is a significant amount of work to get a 155 into an XFS. Apparently you have to relocate the steering tube among other mods... seemed like a lot of work so, I decided to stay away from the 155. Chris told me the largest Skat "drop in" pump is a 150. So, that's what I put in my ski. I don't know how it performs yet, but I'm pumped to get it in the water and try it out.ImageUploadedByTapatalk1371861165.164476.jpg
