yes i do have 300 rank and most of the good equipment ('cept rapier - died with it, am doing dungeoneering atm to get it back ) well on the topic of ma rings let's assume you have the "best gear" for meleeing (i.e. will give the most xp/h) - neitiznot, fire cape, fury, rapier, defender, bandos, barrows gloves, d boots, regular berserker ring - 147 str bonus. you also have turmoil and extreme potions. let's assume you are 98 strength. your max hit will be 578 you can spend about 10-15 hours getting 99 strength, which will increase your max hit to 585 (1.2% increase) or you can spend about 25 hours getting a berserker (i), which will increase your max hit to 589 (1.9% increase) so getting 300 rank is pretty good to get, it gives pretty comparable improvement to the last strength level when divided by the time it takes
