You need a Topper anyway, so just concentrate on making your template first---when you have that done, let`s have a look. Your side hair looks reasonable still... I`d go no higher than medium but don`t worry about the details just yet--John will work with you on that..like you don`t have to have all these figures like percentages, on a list....just send him a few good-quality pics of your remaining hair, and he`ll know what to order for you. If your hairline will be kind of exposed, as in, swept-back hair, maybe go for a Swiss lace front, for better invisibility....you could get the rest of it made from French lace, which is a bit more durable. There`s not a huge amount of ` difference` between the two laces though....a lot of it is down to personal preference after a while. Of course you could get a ` skin` system too...the new super-thin skin, while ` delicate` is very invisible.....though there is the ` standard` [slightly thicker] skin too..personally, I like the breathe-ability of lace, especially in warm weather...... I think a new wearer would be better off going with lace as a ` starter` material, until you get used to bonding-on and suchlike, as you can just do a perimeter bond.......skin normally requires an all-over application of glue and can be tricky to position it and prevent air-bubbles arising during the process.... try a lace system first and see how you get on.
p.s.--you could probably get away with the conventional oval-shaped topper, but as you seem to want some ` extra` coverage around your temples, this will make some small flaps necessary
