Pain at base while pumping

Everything I have tried so far is not working.

Tried different silicon cushions - too tight at base or still get biting pain in base.

Also tried different sleeves and still too much biting pain at base.

Tried 1.75 tube and it was more comfortable at base but it was too small.

Using 2" tube, I get biting pain at base.

Tried using lower pressure (4 HG or less) and get too little pull so no results.

I need at least 5 HG to feel I am doing anything.

Seems like pressure at base is the limiting factor with pumping. Seems like most of pressure is going to the base.

Maybe I need to order a custom cylinder of 1.875" diameter.

Would like to hear from anyone who uses a comfortable pump cylinder with little or no pain at base and what brand they are using.

Also, has anyone tried the following cylinder? If so, is it comfortable at base?

I get pain occasionally but o stop and adjust and start again and it goes away most times.
