If you have a frozen ATPL/A IR then I seriously doubt you have a lot of time either fixed or rotary. A lot of time is 5000 hours plus. If you have a frozen ATPL/A in EASA land then you probably have less than 1400 hours which is sadly not a lot in the current climate. Also unless you want to instruct then few hours are as bad as none, most employers will struggle to insure a low hour helicopter (thank you Whirls) pilot on a single pilot operation.
I fly FW and rotary as do two other pilots here, we don't count the hours in either direction because the jobs are so fundamentally different. You either have the time and qualifications in each area or you don't.
