I can understand your situation cos I'm on the same boat as you.
I was active in bowling for 4 years and stop for 4 years due to
work and studies. I have just restarted a week ago with a new ball
drilled (both my mid and high performace balls have cracked beyond
repair).
If you have picked up bowling through CCA, I'm sure your coach
would have got you started with drills. Kneel down drill, no step
drill, one step drill and so on. If you want to go back to your
previous skill level, there is no easy way out. Work on your
foundation first and your score will soon go up.
I hasbay2005, throw straight for spare but you need not follow
if you have your own style of picking up spares. I bowl straight by
breaking my wrist, it just go straight and never come back.
1 big problem that I am working now, I need to get use to my 15
pds ball. It will take a month or 2 with consistant training at
home and on the lanes.
Good things that I experience for taking such a long break. I
threw aside my wrist guard and focus on training my wrist power (gd
for the yoyo release technique that can impart more revs on the
ball). I learn how to use my power step with a slight change to my
4 step approach. I can balance better now and have a smoother ball
release. Sometimes it is good to forget the bad habits that I used
to have.
Most importantly...have fun bowling!!
