I went there this summer, very nice friendly people but in baggy ff suit i couldnt get off ground on belly and i m about 60kgs. so tried one of their suits and had to fly super big to get off ground, unfortunately airflow didnt seem constant so was tricky. The instructors can do some cool stuff in there and good for floating tourists in but not really for skydive trainning. They mentioned indoor tunnel planned for near riga so that could be good.
