Replying to Mounting-help!

right, ive read all the post on here about mounting already but still am a little confused.........i understand about the principals of mounting forward etc.im about to purchase some trouble maker 175s and want to mount them forward for park and piste riding.i was reading the stuff on k2skis.com and decided thet plus5 was the way to go.but then reading the stuff on here i didnt realise that what is sutable for 1 type of ski isnt for another.so k2 can be mounted up to plus7.5cm. what can troublemakers be mounted up to??i want it to be pritty much middle of the road. eg if they were k2 they would be at plus5cm.
i dont know if that makes sense and was deffinatly a bit long-winded but any help would be cool thanks.
