"HELP" tired Koetsu

Great Forum Gang! MY DILEMA: I have used a Koetsu Rosewood for over 20 years. I have had it retipped once[about 5 years ago and it is tired again. Should I retip it again? or invest in the Shelter 501? I have "never" heard the shelter however; by reading "between the lines" here and elswhere it sounds like it has a similar voicing [tonally] to my beloved Koetsu[lush].I use the Melco table and 2 tone arms 1) sumiko -The ARM and 2)the ET-2[heavily tweaked].The koetsu performs well in both arms. I also have a Stax [12inch model]in the closet somewhere.As I am sure most of us vinyl "dinasaurs" realize arm/cartridge synergy is of paramount importance.Do you think the shelter will work as well as the Koetsu with any or all of these tonearms? The koetsu was magnificent in the ET-2 and was hoping the shelter would be as well.Of course- I am open to other suggestions and recommendations. Cheers David.
