Hi! I own a JS100, and i'm thinking of changing to a JS1000 or some other guitar, but i'm curious about something: i play very very fast on the JS100, wich i believe is mostly due to having learnt on a crappy Maison guitar..i used and abused it almost to the limits, and when i got the JS100 i realized that it was such a better guitar (better neck) that i could play it with much more ease.. so using a bad guitar made me over-skilled

sort-of-saying..
So, after 3 years of JS100's
medium frets i'm thinking of getting a real guitar

with jumbo/warmoth frets.. are they much different than the medium's? will i notice a world of difference? I can't tell just by playng on the store.. it would take me some weeks to now if my playing got better or not..
Any insights?
By the way, is the
neck finish on the JS1000 better? Or it's just the same arm, different frets?
Thanks
