You shouldn't be seeing too many double leg takedowns unless their is an uneven matchup. I've had quite a bit of wrestling experience and not too much Jiu Jitsu experience. From my brief comparison time frame, there are certain aspects of wrestling I need to unlearn and its a bit harder than I expected it to be to unlearn. Fortunately, other aspects of the crossover have more than made up for it, but I think the most important thing is the competitiveness of wrestling has really helped me. What weight will you be wrestling at? I never was big into the throws, but if they are working for you use them. Hopefully you will get a good coach because that makes a huge difference. My first 7 years I had average coaches, but my final 4 I had a former olympic wrestler, who had led several schools to state championships, as my coach. Oh, one more thing. Wear your head gear at all times possible. It may seem like a hassle and you may get made fun of, but don't end up like me with messed up ears.
