colorado 2 inch lift bilsteins and trak rider any thoughts ?

hi, i am lifting the rg colorado 40mm next week, putting bilstein shocks on with pedders trak rider springs front and rear....i was going to use tuff dog springs but after reading that the trak riders are designed and made in australia and use bhp steel i thought thats good enough, and as pedders are going to install the lift kit they said any issues with ride they can adjust or change springs no charge until i am happy, sounds good, they cant do that with tuff dog if i buy the tuff dog thats my call and i'm stuck with them if not happy with the ride, but i still wonder am i doing the right thing should i have stayed with the tuff dog springs, these pedders trak rider are designed specific for the rg colorado so they are not just off the shelf generic..i figure its all good i got the best in shocks cant beat bilsteins, but open to thoughts on springs....thanks.
