Hi, Dont be to quick to asume the fish will be at the bottom of lake/loch/river bed, With this nice weather we have had the last few days ive been out there has been alot of activitiy at the surface, Fishing a floating line with a little emerger on the point and a small nymph on the dropper fishing just in the surface film has produced alot more fish than going down deep.obviously you will have to see on the day and adapt your tactitc to the conditions but just thought id say my bit so you can be prepared to chop and ur change ur taticts to suit the conditions not just be in a mind set to go deep. If your starting off with a dropper for the first time i would recommend using a heavier fly on the point to aid with turn over, As stated above i would leave about 3 foot between dropper and point but as they each to their own, if you ve got the hang of using one fly im sure you ll be ok
