You should be able to make the adjustments yourself. Don't cut them unless there is a huge difference. Lines will always stretch and rarely at the same rate. Depending on what type of set up you have and how much adjustment it allows you can usually do it simply by shortening or lengthening the others to suit (i.e. tie another knot to attach too) If there is a massive difference you might consider throwing another pigtail on the end or something similar. I overcame a 10 cm difference in lines in this way. You could cut and shorten if you had to but I personally would do that as a last resort.

I haven't tried this but the Ozone manual says that you can stretch the shorter ones to match.

From the Ozone manual:
If the lines are not even you must stretch out the shorter lines. Attach the shorter lines to a car hitch or something very solid. Then take hold of the bar and pull with enough force to stretch the line. Do this to any lines that are shorter and re-check that all 5 lines are equal length.

Thanks for the help. have since noticed that the lark heads are noticeably worn so i guess ill replace them as well. unless there are fellow cheapasses on the forum willing to suggest just tying a new knot on these on the unworn part... I can't see any reason why not? its not too dodgy to do this is it? PS i didn't think it would make much difference but I got an 07 LF havoc and haven't actually laid the lines out to check the exact discrepancy yet.
