It seems to me that a rubber crutch tip would negate any floor coupling advantage that an all wood endpin would give.

I remember when most new basses came equipped with wood sockets and pegs instead of adjustable metal rods commonly used today. I think I've still got one of the old all wood endpins I replaced in my junk drawer. The peg has a tang on the top end which was turned on a lathe to fit in a tapered hole in the socket and has a ledge so that the top of the peg butted against the bottom of the socket. The pegs usually were about 1 1/2" in diameter where the peg rests on the socket and it tapers down to less than an inch at the bottom (floor). The tang which fit in the socket are maybe 1/2 at the large end.
