To be honest when I first started using this pattern (Ivor's Olive) it had a fully tied, untrimmed underside (no jokes please Matron
) and caught a lot of fish. Still catches plenty and I personally prefer the 'low riding' version but in fairness, if pulling it or short lining on a loch then, yeah I'd say the fully dressed one might be better.
You'll just have to tie and try both
