This is exactly the conundrum I'm having. Way back in 1998, I replaced my 3 & 5 Adams Tight Lies fairway woods with the Callaway Great Big Bertha Hawkeye 3, 5 & 7 woods with Hawkeye UL Firm Flex graphite shafts. Over the years I have bought & sold numerous fairway metals in the hopes of finding something to replace them. I know the reason I haven't found the right replacements clubs yet is because I have yet to find a shaft that is comparable to the Hawkeye UL Firm Flex graphite shafts.
I'm still looking, but I did pick up the new Adams Tight Lies 3 & 5 woods this
