What clubs do a 3 and 4 hybrid replace?

I just started golfing regularly and i've been using a starter set that includes a 12 degree driver, 16 degree 3W, 22 degree 7W, 3-PW, a SW plus a HLW. Now I bought two hybrids a 20 degree 3 hybrid and a 24 degree 4 hybrid. I bought them to replace the 3Iron because I just had a horrible time hitting it consistently. I wasn't sure which exactly to get so since I got a good deal to buy both and I was able to hit them both pretty well I ended up buying both of them. Now I don't know which clubs in my set I should replace I hit the 3W better than the 7 I'm ok with the 4I and like I said straight junk with the 3I so I'm hoping these clubs work to fill the gap between the 3W and the 4I? Please help this rookie out

In theory,  the 3 + 4 hybrids would replace the 3 + 4 irons - if you have just started golfing regularly, it is doubtful that a 3 iron (and maybe even the 4) will be your friends.

It is possible that the 3 hybrid could also replace the 7 wood. I know my 4 hybrid and 9 wood go about the same distance with the 9 wood having a higher ball flight, but I carry them both because sometimes one works better than the other.

I was actually able to hit the 4 pretty well but if I'm suppose to be comparing hitting that one with hittin the 4H I'm much better with the hybrid. So in theory if I would replace the 3 clubs with the 2 hybrids what would be a good way to fill the last spot in my bag?

No one can give you a hard answer on what to add for a club without knowing the lofts of your PW + SW. My first thought is to add a gap wedge (lofted between the PW + SW), when I bought my irons they came 4-GW, not 3-PW.

Honestly I would rotate out what you have, and if you are not posting scores for an official handicap - carry them all and see which clubs serve the least amount of purpose.

I'd tell you to buy a niblick, but I'd get roasted by everyone else for promoting it as a miracle club.

I'm sorry I should have mentioned the loft of my pitching wedge is 45 and for my SW it's 55. A niblick? Is that like a chipper or putting wedge?

Go with a 50* wedge. A niblick is so much more than a chipper, it is great out of deep rough. My 37* is deadly on the 40 yard *putt* and my 56 allows me to get out of most bunkers with a putting stroke. That said, they are not for everyone.

3, 5 wood

The 3hybrid and 4hybrid are direct replacements for a 3iron and 4iron.
