Can I ask why?
In match situations I really depend on my run up & rhythm but since there is only about 5 odd steps indoor i come in at a curved angle which i think gives me an extra step or two in the run up but also results in going across...most times when i run in indoors I am almost looking at fine leg...not a good habit i know...
also just to add I have had no problems bowling straighter ones and was also finally able to get some inswing in nets on saturday....maybe on March 23rd net I will try and record all these things and post another vid trying to cover other variations...i usually bowl off-stump line with little movement...nets get a little fun where i try and get this bannana curve going...
