Boo,
Which rockets are you talking about,the WgR's or the PB's?
If you search the help and training forum you will find some good imfo on the WgR's,also some helpfull sights to use with them. If your asking about the 190F8's PB rockets,I'd suggest you try to contact Baumer,he's done considerable work with them and has some great tips.
hope this helps!
PS: Baumer may be busy ATM but I'm sure he'll reply to any PM's when he finds the time.
