While I am a nail knot guy and cutt off the loops I know that many like them. Make sure that the loop to loop connection is tied properly. There is an off shore version of the loop to loop that might work better for you as well. Check out the link: http://www.fishandfly.com/articles/20060908_2

If done improperly the leader will cut through the fly line, again, learn to tie a good nail not and never look back. They are slimmer and go through the guides better. Coat with a pliobond or I use UV knot glue for an instant knot on the water and life is good.
