I used to have a front mounted reserve ,,,,,but after one silly silly stupid mistake
when I was talking to somebody.....whilst I was buckling in ...I did not notice that my leg straps were not done up....because I couldnt see them ( the reserve was stopping me see them )....
what followed was something out of a big top trapeze routine ..I dont want to do again..... mine is now mounted behind my head.....I can see clearly now
