Posting higher tier works (Patreon)

Now that some sites like yiff is dead, i hope. SHould i start posting 5$ and 10$ tiers on patreon instead of giving them out as downloadable files? This allows people to see previous tiers, even though i did say if you pledge for a few months you can request the download links for previous works via message. (5-10$ tiers i give u a 3 month/50$ pledge limit before allowing request)
