Thats actually not too bad. A lot of civies has a 1:.75 ratio when starting out. Ok to work you hamstrings more try a couple of twists

1 - on leg press place you feet high on the board. This hit the glute / ham connector

2 - Do leg extensions last and try to fatigue your hamstring quicker


3 - do you have a lying leg curl? I find is stretches the hamstring more effectively thus putting more pressure and strengthing the hamstring more effectively...

4 - Lunges, Lunges, Lunges...go deep with these keeping your forward knee over the heel of your foot. If these hurt your knees that would really suck but it is worth a try.

5 - nice call on the romanian deadlifts...they rule if you do them with good form.

Enjoy and keep on working. You sound like you are well on your way and you see major improvements next spring..
