Thanks for all the replies, guys.
Seville looks like a decent place and quite easy to get to - that sounds like it could be the right DZ for a week trip here and there.
Do you think I should avoid talking about base there or would it be OK? When I got my A-licence (ten years ago) it wasn't something you could speak about at the DZ, one of the fun jumpers went and did a bridge jump somewhere or other and "got in trouble" over it. Maybe a large DZ like Seville is more open to it these days, though, right?
You see - as you guys mention - I would need to tailor my jumping towards base-relevant stuff so I'd rather be honest with them. I am also interested in doing FS1 as well while I'm there, probably, just to tick that, but otherwise quite happy to do dozens of hop 'n pops and get great at landings. Tracking, too ^ as just mentioned. I would happily pay for a coach for all of these things, and it sounds like they have coaches available.
WRT to canopies - I will probably hire whilst there, initially. I guess for the first trip (they are open 5 days per week) I might get in a few dozen jumps so maybe any large "student" canopy would suffice and I can work out which base-like canopy to move into in due course.
Should I avoid jumping my BJ for a while yet, i.e. save it for a few dozen plane jumps maybe much later on? Don't want to wear it out, right?
Cheers, guys
